Which of the following best explains the reason for taking three measurements at each light intensity instead of a single measurement? Select one or more: a. By taking three measurements at each light intensity, the investigator could identify any result that was not expected and repeat the measurements until the expected result was obtained. b. By taking three measurements at each light intensity, the investigator could eliminate any result that did not support the hypothesis. c. By taking three measurements at each light intensity, the investigator could be more confident in the accuracy of the measurements than if the measurement had been made only once.

A student in PY106 decides to build a rather strange circuit using two batteries (9 V and 3 V) and two resistors (1 Q and 2 Q) as shown in the figure below. They want to calculate the current flowing around this circuit (in the direction shown in the figure) but are not quite sure how to start. Don't worry, Kirchhoff's Rules to the rescue! Assuming we travel around the circuit in the clockwise direction (starting at point a and moving up through the 9 V battery), how would we write Kirchhoff's Loop Rule? I C. 10 9 V 3 V d
